The difference with the pine, which are very common and mostly does well on poor sandy soils, is very obvious.

As preparation for the distillation, I cut the branches into smaller pieces of mostly young twigs with needles.

After having stuffed the Alembic with freshly cut spruce branches distillation could begin. At a temperature of about 90 degrees Celsius (in the top of the alembic) the first drops came from the cooling bucket

Setting the cooling gave no problems and after more than two hours, I stopped distilling.At that point there was no oil left, and I had six bottles filled with hydrosol.

The amount of spruce branches in the alembic was not weighed. So a exact yield was incalculable. What I know is that I filled the alambic with about 7 liters of spruce twigs and distilled about 7 mL of essential oil.

The oil had a very surprising pleasant smell. I had expected a more pine-like odor. The spruce essential oil had a citrus odor. If you read the books about it is this true. Fir needle oil contains pinene Santen and over 30% limonene, a terpene that a major constituent of citrus oils. Reason enough for me in the near future to distil more conifer species .
